Hortifeeds Citric Acid

For acidification of irrigation water to reduce carbonate deposits and maintain availability of nutrients. Citric acid also has a complexing action on many nutrients which improves their availability, uptake and mobility.

Add citric acid in sufficient quantity to reduce the water pH to between 5.5 and 6.5.

The amount of acid required will vary with the bicarbonate content of the water - see application rate table.

Application Rate

Below is the amount of Citric acid needed to react with bicarbonate in irrigation water per 100 litres of stock solution, for dilution at 1:100 (1%) to produce 10 000 litres of pH adjusted fertigation solution
